The USB Bit Whacker is a spectacular little development board
featuring the PIC18F2553. Based on the work of Brian Schmalz, the UBW is
a small board with a command interpreter for basic input and output
control. When attached to a Windows/Max OS X/Linux computer, the UBW
will show up as an RS232 Com port! You control the individual I/O pins
on the PIC through simple serial commands. Board comes fully tested,
preprogrammed, and assembled as shown.

The 18F2553 also comes pre-programmed with a USB bootloader. This means
you can create HEX files using any compiler or assembler (C18,
CC8e,
SDCC) and
then load that HEX file onto the PIC without an external programmer -
directly over USB! Power is obtained over USB.

Please download the Microchip USB Bootloader below. Please see the UBW
home page for more information.

You may start with downloading and installing the latest release of
Microchip USB Framework Installation file. The Release Notes provide
details on the location of the Comunications Device Class (CDC) RS-232
Emulation driver INF file location. When installed the S1 LED will begin
to blink.
